@Exodia so what is your answer?

@Exodia said:Sorry man, I mis read the question and took D on AC. My mistake!!
Answer is 35 root(2). using sine law to find it.
AD/sin 30 = CD/ sin 45
35 x 2 = CD x root(2)
CD= 35 root (2)
AD/sin 30 = CD/ sin 45
35 x 2 = CD x root(2)
CD= 35 root (2)
@veertamizhan said:ABC is a right angled isosceles triangle with angle B being 90. If D is a pont on AB so that angle DCB = 15 and AD = 35cm, find the length of CD.
35 rt(2)

@veertamizhan said:@Exodia thanks anna. and can you calculate DB with the available information?
If you can know the trigonometric formulas yes you can .
You'll need values of sin 75 or sin 15, which can be calculated using half angle formulas etc used in trigo..
@veertamizhan said:@Exodia thanks anna. and can you calculate DB with the available information?
Apply sine rule to DBC:
CD/ sin 90 = DB/ sin 15
DB= 35/2 (root(3)-1)
CD/ sin 90 = DB/ sin 15
DB= 35/2 (root(3)-1)

ye time ke sare Q aise hi lagte hai mujhe..
In triangle ABC, AB=6 and AC=9. AD is the internal angle bisector of angle A and D lies on BC such that BD=2, and CD=3. Find the length of AD.

no . this question is not making any sense
see i took total amount of work = 72 units
so per day b1 does = 4 units
b2 = 3 b3 =2
they finish the work in 26 days
so (4+3+2)*26 = 9*26 = way beyond 72 what i had assumed.
ok i forgot everthing and started with this
what i took was that they wont work according to their efficiency
they do 24 units(as it is given every one does equal amount of work) of work in 26 days
so that means 24/26 = 12/13 units of work is done by each of them in 1 day
so in second case one day work of b1 and b3 is done by b2
so it shold be 24/13 amounts works that is extra done by b2
which is not in the option and which is totally absurd too 😁 😁
pls pst the solutin. please post it in the way you post question. last time i had to tilt my head to understand the solution 😞
